Maintenance
7.3 Replacing the seat and
plug
Risk of regulator damage due to excessively
high or low tightening torques.
Observe the specified torques on tightening
regulator components. Excessively tightened
torques lead to parts wearing out quicker.
Parts that are too loose may cause leakage.
Observe the specified tightening torques.
Make absolutely sure that no torque is ap-
plied to the bellows seal (5.1) during assem
-
bly or disassembly. Otherwise, the metal
bellows will be destroyed.
On disassembling the valve, push the cotter
pin of the travel stop cap (see Fig. 3) to "un
-
lock". Push it back again to "locked" on re
-
assembly. See also the note on the cross-
beam (8).
